How Accurate Are The Best Glucose Meters

How Accurate are Blood Sugar Monitors?

Youd be forgiven for thinking that all glucometers have FDA clearance because they are medical devices, but that isnt always so. The 2018 FDA draft guidance for personal use glucose meters will require:

  • 95% within +/- 15% across the measuring range
  • 99% within +/- 20% across the measuring range

Research conducted by The Diabetes Technology Society Blood Glucose System Surveillance Program found that accuracy varied widely between the major home blood glucose meters. At present, they are considered clinically accurate if the reading is within 20% of what a lab test would indicate. The quality of the glucometer and compatible testing strips can impact the overall accuracy of your blood sugar monitoring test.

How accurate your glucometer is depends on the quality of the device itself and the quality of compatible test strips. Wed also recommend checking the instructions for the meter to see what substances might interfere with blood sugar reading accuracy.

Finally, store the glucose meter and test strips according to the manufacturers instructions, as incorrect storage may also impact accuracy of readings. Test strip vials, for example, should be closed when stored. This is backed by research , published by the National Library of Medicine, that showed how test strip stability lasted longer for closed vials than open vials.

Is It Safe To Use Someone Else’s Glucose Meter

Yes, but it’s always good to use your own glucose meter rather than share it with someone else. If you have to share the glucose meter, the device should be cleaned and disinfected before taking readings. However, it isn’t easy to save your data because someone else may have his/her own sugar level history already in the device.

Be Generous With Your Sample

To minimize pain and inconvenience, most meters can produce a reliable reading with a portion of a microliter of blood. However, a more generous sample raises the likelihood of an accurate test.

What if you didnt apply enough blood the first time? A handful of test strips and meters can accept a second drop, but the majority cant produce correct results with reapplication. Instead, youll need to get a new test strip and apply a generous sample.

You have to consider many factors when testing your glucose levels, but the one thing you should be able to trust is your meters programming. Thats why MedEnvios Healthcare offers the most reliable devices. For more information, give us a call at or visit us online.

A wearable blood glucose monitor or a CGM is capable of measuring blood sugar levels using sensors. Dexcom CGM system is one of the best wearable glucose monitors that measure blood glucose levels 24 hours a day. It is a CGM that consists of a tiny sensor that measures glucose level, a transmitter that transmits data to the display device, and a smart device that displays real-time information. The sensor tracks the glucose level in your interstitial fluid and the sensor is capable of testing the level of blood sugar every few minutes. The sensors present in a continuous glucose monitor can change the tracked information into electrical signals and can display it.

Frequently Asked Questions On Glucose Meters

While it ultimately depends on your glucose meter, generally speaking, your meter should be replaced if its older than five years. There will be instances in which your meter may last shorter or longer than that, but that is the average age at which meters should be replaced. Always speak with your doctor about whether or not you should upgrade. Be on the lookout for new meters that have new features and that you can get at a lower monthly cost. Once again, a doctor may be able to provide insight into making the switch to a newer model.

Most glucose monitor kits come with a test solution that will allow you to test for accuracy. The testing procedure will involve squeezing a drop of the solution onto a test strip, inserting it into the monitor. Compare the amount of glucose you see with the amount printed on the solutions bottle. If the numbers align, your glucose meter is working properly. Test your meter each time you open a new box of test strips or as often as the meter supplier suggests. If you ever receive a blood sugar reading that seems off, test your monitor to see if there is an issue.

In some instances, the strips may have been compromised through extreme heat or cold. Try a fresh pack of strips and see if that does the trick. If not, speak with your doctor about potentially finding a new blood glucose meter.

General Accuracy And Variance Criteria

Blood glucose test results are used by people with diabetes to make critical decisions about their treatment therefore, it is important that the results are accurate so that nutritional and drug dosing errors are better avoided, explains the FDAs guidance document.

For any glucose meter seeking FDA-approval, studies should demonstrate that 95 percent of all blood sugar level results are within 15 to 20 percent of the blood lab value.

The acceptable 5 percent of results that are greater than a 20 percent variance should be explained in detail by the manufacturer to justify why the errors occurred. Reasons might include an extremely large number of tests or patients using the device incorrectly by not washing their hands before testing, etc.

Test On Your Fingertips

The fingertips are the recommended testing site, though many meters allow you to test on alternate sites such as the arms or palms. If you get consistent readings, this is fine. However, if youre worried about a rapid change in your blood sugar, make sure to test on your fingertips the fingertips are the most accurate site because blood circulation is faster there than other areas.

Of course, repeatedly testing on your fingers can be painful and lead to callouses. One way to minimize pain is to choose a different finger every time you test. Additionally, avoid pricking the pad of your finger, which has sensitive nerve endings. Instead, try testing on the very tips of your fingers, close to your nails.

Notes For Buying Online

When browsing for glucose monitors online, youll notice that some versions, such as the Rite Aid TrueMetrix, are available for purchase over the counter, while CGMs, such as the FreeStyle Libre or Dexcom G6, are not.

This is because youll need a doctors prescription to get a CGM system. However, you dont need a prescription for the basic fingerstick meters weve included on our list. With a prescription, you may be able to buy a CGM from a medical supply store online.

If you do decide to purchase a glucose monitor or meter online, be sure you know the total costs up front, including any test strips, extra sensors, lancets, and accessories that may be sold separately. You might also consider setting up these accessories on an auto-ship basis so you dont run out.
